Swivel cups will keep your springs happy during travel by allowing rotation and angular alignment. They work with our hollow screw jacks or you can run them on a stud on the rearend. Instead of a bolted together combo, our cup comes off by simply pushing the SLIC pin. This Patented SLIC Pin tehnology makes spring changes a breeze.
4" spring cup and a 3/4" O.D. x 8" Long weight jack bolt for a lightweight combo.
